[go-nuts] why defer function with parentheses

[Tamás Gulácsi]

Defer defers the esecutiin of the following expression, but not the evaluation 
of the arguments.
So "defer fn(a==1)" will call fn when this function exists, with a bool that is 
true iff a _was_ 1 when the defer was registered.

[go-nuts] why defer function with parentheses

[Flying]

example :
fn := func() {
 fmt.Println(10)
}
defer fn()


my question is why use defer fn() not defer fn


when we use fn() here doesn't it mean call it now ???
